forceModel_ArchimedesIB command

Syntax:

Defined in couplingProperties dictionary.

forceModels
(
    ArchimedesIB
);
ArchimedesIBProps
{
    gravityFieldName "gravity";
    voidfractionFieldName "voidfraction";
}; 

• gravity = name of the finite volume gravity field
• voidfraction = name of the finite volume voidfraction field

Examples:

forceModels
(
    ArchimedesIB
);
ArchimedesIBProps
{
    gravityFieldName "g";
    voidfractionFieldName "voidfractionNext";
} 

Description:

The force model performs the calculation of forces (e.g. fluid-particle interaction forces) acting on each DEM particle. The ArchimedesIB model is a model that calculates the ArchimedesIB' volumetric lift force stemming from density difference of fluid and particle. This model is especially suited for resolved CFD-DEM simulations where the particle is represented by immersed boundary method.

Restrictions:

Only for immersed boundary solvers.
